 ### Set the underlying media player
-When the [Source](mediaplayerelement_source.md) property or [AutoPlay](mediaelement_autoplay.md) property is set on MediaPlayerElement, it will automatically create an underlying [MediaPlayer](../windows.media.playback/mediaplayer.md) if one doesn't already exist. Alternatively, the user can create their own [MediaPlayer](../windows.media.playback/mediaplayer.md) and set it on MediaPlayerElement using the [SetMediaPlayer](mediaplayerelement_setmediaplayer_932380017.md) method. Here's example of how to set the underlying [MediaPlayer](../windows.media.playback/mediaplayer.md) in code.

 > Setting MediaPlayerElement properties will set the corresponding properties on its underlying [MediaPlayer](../windows.media.playback/mediaplayer.md). You have the option to use the underlying [MediaPlayer](../windows.media.playback/mediaplayer.md) directly instead of using MediaPlayerElement properties. Be aware that using [MediaPlayer](../windows.media.playback/mediaplayer.md) directly where an equivalent MediaPlayerElement property could otherwise be used can cause unexpected behavior. This is because the MediaPlayerElement is not aware of everything happening to its underlying [MediaPlayer](../windows.media.playback/mediaplayer.md). For example, if you set the source directly on [MediaPlayer](../windows.media.playback/mediaplayer.md), then MediaPlayerElement's [Source](mediaplayerelement_source.md) property will not reflect the change. For this reason, you must be consistent in using MediaPlayerElement properties or directly using the underlying [MediaPlayer](../windows.media.playback/mediaplayer.md). This documentation will use MediaPlayerElement properties whenever possible.
 
 ### Detach the underlying media player
+
 The [MediaPlayer](../windows.media.playback/mediaplayer.md) is detached from MediaPlayerElement when the MediaPlayerElement is destroyed or when a new [MediaPlayer](../windows.media.playback/mediaplayer.md) is set using [SetMediaPlayer](mediaplayerelement_setmediaplayer_932380017.md). When detached, MediaPlayerElement treats the underlying [MediaPlayer](../windows.media.playback/mediaplayer.md) differently depending on whether it was created by MediaPlayerElement or set using [SetMediaPlayer](mediaplayerelement_setmediaplayer_932380017.md).
 
 If the [MediaPlayer](../windows.media.playback/mediaplayer.md) was created by MediaPlayerElement, it will properly [Close](../windows.media.playback/mediaplayer_close_811482585.md) the [MediaPlayer](../windows.media.playback/mediaplayer.md) for you.
